The content on that page is too AI-generated to make sense to me; I don't understand what the model is for.

I have the same question.

I get that it’s designed to run on a CPU, big GPU or MacBook (although the way that was phrased confused me at first).

I’m struggling with what a “decoder-only” model is good for.

AI doesn't want anything, so it doesn't care whether it conveys meaning in its writing. And, apparently the developers of this project also don't care whether it conveys meaning. They just assume we'll wade through the slop? I dunno.
